Basics of Apple Device Security AN OVERVIEW FOR MAC, IPAD AND IPHONE Basics of Apple Device Security SMALL BUSINESS A well-planned cyberattack or an accidental download of 2 malware can mean the difference between a productive day and all work grinding to a halt. As hackers get more sophisticated, organizations concerned about their bottom line and security of their customer, employee or student data must stay on top of security. This guide is for anyone that has been tasked with Apple security concerns, like all IT security concerns, are real. managing Apple devices in your organization and wants to get serious about their organizational While Apple has invested a great deal in its security features security of their Apple devices, and offers basic and has rapidly become the leader in device and data privacy information for newcomers or a simple refresher for and security, no operating system is immune to security Apple management veterans. challenges. This means that administrators must not only respond quickly to security issues, but also proactively guard against them. 3 The basic building blocks Several factors work together to ensure the security of your organization’s hardware and data, and you can break them down into six main areas: Securing devices Apple native security Data encryption Keeping your physical devices Security systems already built-in The basics of encrypting data at Introduction secure and protecting those to macOS, iOS and iPadOS rest and data in transit using them to Apple Page 4 Page 7 Page 6 Security Compliance Secure monitoring Application security deployments and patching Monitoring devices to pinpoint Deploying with the highest level needed updates Keeping up-to-date software of security available Page 8 Page 9 Page 11 4 Building Block One: Apple Native Security How to make the most of them with device management Security features already built in to macOS (operating system for Mac) amd iOS (operating system for iPhone) and iPadOS (operating system for iPad) are extensive and come with several benefits: Apple operating systems are based on a UNIX foundation, a very well-researched and developed foundation with excellent stability Strong OS security framework Device security in the form of locking and device finders Ability to implement and configure security controls through configuration options via mobile device management (MDM) An MDM solution can take these existing security configurations and deploy (and enforce) them to a large group of devices. So, you can set up not only one Mac or iPad securely, but thousands. You also have more expansive security controls with an MDM tool that can lock and wipe devices that are lost or removed from the facility. 5 Security feature details Native security features for macOS, iOS and iPadOS macOS Security Features iOS Security Features iPadOS Security Features 1 Software System Integrity Gatekeeper Software Secure System App Store Software Secure System App Store Updates Protection (SIP) Updates Updates App Store FileVault XProtect Touch ID Hardware App Touch ID Hardware App Encryption Encryption Sandboxing Encryption Sandboxing App Sandboxing Privacy Settings Privacy Supervision Remote device Privacy Supervision finder for lost devices 6 Building Block Two: Securing Devices Tracking, securing and protecting devices and users Securing or restricting devices manually: One of the simplest ways to damage an organization’s security or to compromise end-user’s safety is through access to a single Mac iPad and iPhone device. Whether your organization serves healthcare workers, remote staff, retail floor employees or frequent travelers — at any Require passwords on all devices Require passwords on all devices given moment your devices could be in twenty different places.

The damage can be incalculable: a Track all Mac serial numbers Report to Apple online if a device has thief manages to find private student data from a lost laptop or Report to Apple online if a device has been been lost or stolen accesses the entire organization’s database from that laptop. A lost or stolen Enable parental controls on an individual former employee who still has her work laptop making private Enable parental controls on the device to device, creating different accounts for information public or offering it to competitors. Even a malware block websites (Only affects Safari browser) each device introduction from a remote source. Set and deploy all Restrictions and security Set and deploy all Restrictions and features from first use or setup with Blueprints security features from first use or setup Devices get lost and stolen. Accidents and moments of Lock or wipe any lost or misused with Blueprints inattention happen, and planning with the assumption that the device centrally Lock or wipe any lost or misused question is only when someone will lose track of a device is vital. Set up password requirements to deploy device centrally to all devices Set up password requirements to deploy In addition, many devices — especially those shared by multiple Manage and push OS Updates centrally to all devices users — require safeguards against misuse, accidental discovery Manage and push OS Updates centrally of another’s data, or viewing of inappropriate content. 7 Building Block Three: Encrypting Data Disc or device encryption. MacOS already has built-in disk encryption: FileVault. You don’t have to add any additional software in To manually enable FileVault: order to encrypt a drive on a Mac. 1. Navigate to System Preferences > Security and Privacy > FileVault FileVault is FIPS 140-2 certified. That means Apple’s 2. Select the toggle switch to turn on the option from there encryption system meets the highest standards for 3. Repeat federal government encryption. You can enable FileVault manually or remotely: user To enable FileVault across your organization’s devices, leverage an MDM solution to automate, deploy and enforce encryption. You can deploy a Blueprint that will enable can choose the option themselves on one device, FileVault, and IT can retrieve encryption keys in case staff need to de-encrypt the or IT can enable FileVault (using Jamf Now) across device down the road. hundreds or even thousands of devices in one session. 1. Create a Blueprint through a simple selection of options within Jamf Now and select “Enable FileVault” as a setting Jamf Now ensures that encryption keys are centrally Deploy to as many devices as you’d like stored in case you need to uncover data, someone 2. leaves or someone forgets their password. 3. There is no step three With Jamf Now, if a device is enrolled and has FileVault enabled through the MDM, recovery keys are stored centrally on the device details page in case IT needs to gain access. What about an Encrypting iOS and iPadOS devices is even easier. iOS and iPadOS devices have built-in encryption as soon as a passcode is set. You can do this individually, or you can do it from Jamf Now, as well as setting up parameters for the passcode such as iPad or iPhone? length and complexity. 8 Building Block Four: Compliance Monitoring Ensure that protocols and controls are in place on all devices A security system is only as good as its weakest point. For the best coverage, administrators must monitor the organization’s devices to ensure that every device is updated, has received the most recent patches, and has the correct encryption options enabled. Monitoring compliance with Jamf Now: To ensure that all of your organization’s devices are protected Monitoring compliance manually: through Jamf’s inventory feature: To ensure that all of your organization’s devices are protected, you would need to constantly audit devices. 1.

This is the only way to get apps on an other hostile code. If iPhone or iPad, which controls security. Confining Mac users to the App Store for their apps is a way that administrators can control security device-wide.

  • How to Disable Gatekeeper and Allow Apps from Anywhere in Macos Sierra
    How to Disable Gatekeeper and Allow Apps From Anywhere in macOS Sierra Gatekeeper, first introduced in OS X Mountain Lion, is a Mac security feature which prevents the user from launching potentially harmful applications. In macOS Sierra, however, Apple made some important changes to Gatekeeper that seemingly limit the choices of power users. But don’t worry, Gatekeeper can still be disabled in Sierra. Here’s how. Stand out at the party or promote your business with colorful powder coated and custom engraved Yeti tumblers from Perfect Etch. Traditionally, Gatekeeper offered three settings of increasing security: anywhere, App Store and identified developers, and App Store only. The first choice, as its name describes, allowed users to launch applications from any source, effectively disabling the Gatekeeper feature. The second choice allowed users to run apps from the Mac App Store as well as from software developers who have registered with Apple and securely sign their applications. Finally, the most secure setting limited users to running apps obtained from the Mac App Store only. While the secure options were good ideas for less experienced Mac users, power users found Gatekeeper to be too limiting and typically sought to disable it by setting it to “Anywhere.” In macOS Sierra, however, the “Anywhere” option is gone, leaving “App Store” and “App Store and identified developers” as the only two options. Disable Gatekeeper in macOS Sierra The Gatekeeper settings can be found in System Preferences > Security & Privacy > General. The Gatekeeper options are located beneath “All apps downloaded from:” with the choice of “Anywhere” missing. Thankfully, the “Anywhere” setting can be restored to Gatekeeper in Sierra with a Terminal command.

  • Apple at Work Deployment and Management White Paper
    Apple at Work Deployment and Management Simple to deploy. At any scale. Apple makes it easy for IT teams to administer devices, manage their configuration, distribute apps and content, and secure corporate data. With Apple Business Manager, devices can be distributed directly to employees and used right out of the box, all without manual configuration. And with flexible deployment models across all Apple platforms, IT can get employees up and running faster than ever with the best tools for the job. Management made easy Apple devices have a built-in mobile device management (MDM) framework, making it easy for IT to deploy devices, distribute apps and books, configure settings, and ensure the security of each device. Paired with a third-party MDM tool, IT teams can remotely manage and update devices over the air. And if devices ever go missing, IT teams can remotely and securely erase them. MDM supports configuration for apps, accounts, and data on each device. This includes integrated features such as password and policy enforcement. Controls remain transparent to employees while ensuring their personal information stays private. And IT maintains necessary oversight without disrupting the productivity employees need to succeed. Whether a business uses a cloud-based or on-premise server, MDM solutions are available from a wide range of vendors with a variety of features and pricing for ultimate flexibility. And each solution utilizes the Apple management framework in iOS, iPadOS, tvOS, and macOS to manage features and settings for each platform. Zero-touch deployment Apple Business Manager is a web-based portal for IT administrators to deploy iPhone, iPad, iPod touch, Apple TV, and Mac, all from one place.
